Industrial USB to RS485 Converter

รายละเอียด รหัสสินค้า: EFDV748 ยี่ห้อ: Waveshare รุ่น: Industrial USB to RS485 Converter This is an industrial USB to RS485 converter with original FT232RL inside. It features embedded protection circuits such as lightning-proof, resettable fuse, ESD protection, and TVS diode, etc. It's pretty small in size. Features : USB to RS485 communication Adopt original FT232RL, fast communicating, stable and reliable, better compatibility Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance 3 LEDs for indicating the power and transceiver status Specification : Product type: industrial converter Baudrate: 300-921600bps Host port: USB Device port: RS485 USB: Operating voltage: 5V Connector: USB-A Protection: 200mA self-recovery fuse, ESD protection Transmission distance: about 5m RS485: Connector: screw terminal Pins: A+, B-, GND Direction control: hardware automatic control Protection: 600W lightning-proof and surge-suppress, 15KV ESD protection (onboard 120R balancing resistor) Transmission distance: about 1200m (low rate) Transmission mode: point-to-multipoints (up to 32 nodes, it is recommended to use repeaters for 16 nodes or more) LED indicators: PWR: red power indicator, light up when there is USB connection and voltage is detected TXD: red TX indicator, light up when the USB port sends data RXD: red RX indicator, light up when the device ports send data back Operating environment: Temperature: -15℃ ~ 70℃ Humidity: 5%RH ~ 95%RH Operating system: Mac, Linux, Android, WinCE, Windows 10 / 8.1 / 8 / 7 / XP
